Hi there,
Same issue for me in a my 15 ipa-servers multi-master grid just after
the update.
The replication is completely broken except on 3/15 nodes.
This is the second time I have to fully reinitialize the whole cluster
for similar reason. I don't know what to do to clean this mess...
For more information: this cluster has been initialized on a fedora
4.1.4 more than one year ago then complemetely migrated to Centos 7,
IPA 4.2.
what is the exact version of 389-ds-base you are running ?
did these errors come out of the blue or are they related to some
activities ? The csn which is not found has a timestamp of "Thu, 22 Sep
2016 15:59:08 GMT" did anything happen around this time ?
Example on fr-master03 error logs:

Hello. I have four IPA servers replicating in full mesh. All
four servers are running ipa-server-4.2.0-15.0.1.el7_2.19.x86_64.
This was working for some time but now I see that no replication
is occurring automatically at present.
When I update a user attribute on an IPA server, I see errors like
these:
[22/Sep/2016:16:53:49 -0700] attrlist_replace - attr_replace
(nsslapd-referral, ldap://ldap03.xx.com:389/o%3Dipaca) failed.
[22/Sep/2016:16:58:56 -0700] NSMMReplicationPlugin -
agmt="cn=masterAgreement1-ldap03.xx.com
<http://masteragreement1-ldap03.xx.com>-pki-tomcat" (ldap03:389):
Incremental update failed and requires administrator action
I can reinitialize without errors.
ipa-csreplica-manage re-initialize --from=ldap01.xx.com
<http://ldap04.us.oracle.com>
ipa-replica-manage re-initialize --from=ldap01.xx.com
<http://ldap01.xx.com>
Afterwards I see my attribute (and other) changes are replicated
on each server I re-initialize from. But subsequently,
replication doesn't seem to be happening.
I reinitialized according to the steps in Table 8.7, "Replication
Errors", but subsequent replication isn't occurring. Any
suggestions? Is it safe to identify one of my four servers as
containing up-to-date data, then sever and reinstate replication
relationships with the other three?
